(54) Chemical analyzer and structure for chemical analysis


(57) An analyzer and a structure for analysis with high performance are provided which can reduce contamination between the reagents when the valve components or a plurality of reagents are included.
The present invention is a chemical analyzer (1) to which a sample is introduced and into which a structure (2) for holding a reagent reacting with the above described sample is housed, including a mechanism for detecting the above described sample after the above described reaction; in which the above described structure includes a reagent cartridge (20) having reagent storing parts for storing a plurality of reagents, a connection part to which the above described reagent cartridge is connected, and a channel cartridge (30) having reagent channels through which a plurality of the above described reagents flow, a sample channel through which the above described testing object flows, and a reaction region where the above described reagent is reacted with the above described testing object.
